Contact breaker wire.

On the later models with coil ignition the wire from the contact breaker exits through the rear of the outer timing cover. The coil is mounted on the frame, under the tank. Which way is the cable routed between the coil and the contact breaker?

Hi

From the CB cover across to a convenient hole in the RH engine plate, back under the cover to the frame down tube, up the down tube and forward along the top tube to the coil. This is as per the original loom.

Thanks, Mick. That helps but that wire does look vulnerable. I'll look at putting it in some sort of sleeving. According to the 1960 parts list, the rubber grommet is #024159. That's not listed on the AMOC Spares website. Any idea where I might obtain one?
Thanks, John.

Hi John

Steve at AMC Classic supplied mine under that part number.

Agree it does look a little exposed but I try to keep things looking original where I can - unseen in the photo are about three layers of heat shrink tubing which make up the difference in diameter between the wire and orifice in the grommet and provide a water seal. Still looking for a suitable split rubber tube to stop the wire potentially chaffing as it goes through the engine plate.

Regards Mick
